RAM puzzle

Hi all,

recently I bought 2 x 1 GB modules 1024MB SO-DIMM OCZ PC400 CL2.5. I plugged them into my Debian Asus M6726NW laptop. I was surprised to see that on /proc/meminfo I have only:

MemTotal:       906692 kB

Looking at lshw I have:

description: 	System Memory
physical id: 	
slot: 	System board or motherboard
size: 	2GB
capacity: 	3GB

So, what do you think is the problem? Are my new RAM modules malfunctioning, or is that some software problem? In both cases, how lshw sees the right amount of memory, but the kernel does not?!
